Electrical lightning contral
Lighting controls are input/output devices and systems. The control system receives information, decides what to do with it, and then adjusts lighting power accordingly.
Here we see a basic lighting circuit (switch leg). Power travels along the circuit to energize a group of lights. This lighting system supplies illumination.
Building automation
Building automation is the use of automation and control systems to monitor and control buildingwide systems, such as HVAC, lighting, alarms, and security access and cameras. Converging these systems into a single IT-managed network infrastructure creates a smart building. Smart buildings often use Power over Ethernet (PoE) to power and connect IoT devices and sensors.
Information Security
Infomation security responsibilities include establishing a set of business processes that will protect information assets, regardless of how that information is formatted or whether it is in transit, is being processed or is at rest in storage.
Powertel applies information security to guard digital information as part of an overall cybersecurity program.
infosec's three primary principles, called the CIA triad, are confidentiality, integrity and availability.
In short, infosec is how you make sure your employees can get the data they need, while keeping anyone else from accessing it. It can also be associated with risk management and legal regulations.
